feedback, pls. d3/6, access

Could anyone with D3/6, BDE or ADO experience
with any Access (97 pref.) give me some feedback on
how good of a solution this is?  I am in the process of
moving a large app (hundreds of fields in dozens of
tables) to Access...and want to make sure I'm making
a good decision.

This is a multi-user threaded app (Voice application)...
and speed/stability is important.

Thanks,

David Beyer
